Well creekbend now that I'm a little less angry, here goes My Montana has been wonderful and I hadn't had any problems with until one day I'm going to mow my orchard, Get the tractor out in orchard engage the PTO step on the pedal to start mowing and then a grinding sound and the tractor doesn't move. so finally get to the dealer, they split the tractor and tell me that HST is toast and it will be $4400.00 to fix it with no warrantty and I should really purchase a new one for $8000.00 and some change and a 5 year warranty. I would like to know if the HST is really that expensive, I can't pen down a part number and price the unit, and is it a task that I could do myself. And I do have friends that are really good mecanhics that could help me.
